Well, this is a fairly easy one. It would have to be the KCs and KDs as I grew up with these, and tended to travel on more than I did with the Ds. The times I was on a bus into town or home from town, it was usually a KD. I don't recall haing travelled on a D. I was on two on a trip to Dublin Zoo when I was in Junior infants, but I have no other recollection if having been on anymore. I am referring to the Vanhool Ds, as C/Road didn't have Standard Ds  in C/Road when I was a kid. Having said that, I would like to see both variants of D back just to be able to travel on more of them. I would also like to see the RHs back. I loved them as I think the green seats reminded me of the KCs and KDs, and also the engine sound was great. Out of the three classes of Olympian, these were my favourite and I thought they had more character.

I'd also like to see the likes of the Ps, ADs and VAs back. I was only ever on the one P, so it would be nice to travel on more. I have been on some ADs, and possible all of the VAs. I can't remember if I ever travelled on VA2 and VA3, or I did travel on one, but not both. I think I preferred the sound of the ADs to the VAs, but both were great. I  guess I'd like to see the buses I grew up with back in service, even if I never travelled on the class. So, the likes of the MBs, any of the Merc Imps and the VLs I'd like to see back, as I was never on these. I was on one 93-D ME on the 123 before, but that was way back. I have no complaints with what we have now, but I sort of miss the old days when the streets were adorned with green, core (or a mixture), Imp and City Swift liveried buses.
